Book Description
Biphasic Chemistry and The Solvent Case examines recent improvements in reaction conditions, in order to affirm the role of chemistry in the sustainable field. This book shows that those who work within the chemistry industry support limits for the use of toxic or flammable solvents, since it reduces the purifications to simple filtrations. Thanks to commercial scavengers, solid phase syntheses are now available to all. Fluorine biphasic catalysis enables extremely efficient catalyst recycling and has a high applicability potential at the industrial level. This book also reviews the many studies that have shown that water is a solvent of choice for most synthetic reactions. Particular traits can be obtained and the effects on thermodynamics make it possible to operate at lower temperatures, thereby achieving energy savings. Finally the great diversity of application of the reactions without solvents is illustrated.

Book Description
Enzyme dysfunction, an essential catalyst for the smooth running of biochemical reactions and the maintenance of vital processes, is at the root of many pathologies that have paved the way for the development of numerous drugs. Aimed at pharmacists, biologists, biochemists, doctors, veterinarians, medicinal chemists and students from a wide range of disciplines, Enzymes and Drugs brings together, for the first time, extensive documentation highlighting the relationships between a large number of drugs and enzymes. The book also highlights new prospects for therapeutic discoveries offered by enzyme targeting. Numerous applications have been developed thanks to strategies for studying enzyme inhibition or activation, as well as the development of allosteric effectors, presented with their advantages and disadvantages. Various rare diseases, known as "orphan" diseases, have resulted from enzyme deficiency or absence. For their treatment, the introduction of substitute enzymes has led to major therapeutic advances.

Book Description
This book offers comprehensive information on the fundamentals and applications of ionic-liquid-based aqueous biphasic systems, which have predominantly (and successfully) been employed as alternative platforms for the extraction, separation and purification of diverse high-value products. The book consists of an initial introduction providing a brief overview, from fundamentals to applications, followed by nine chapters addressing the respective phase diagrams (interpretation and characterization) and remarkable examples of their applications. It also includes two final chapters focusing on recent developments in the search for more environmentally-benign and biocompatible ionic-liquid-based aqueous biphasic systems, and on the progress made to date concerning the recovery, recycling and reuse of the phase-forming components, the goal being the development of cost-effective and sustainable processes. The book offers an interesting and useful guide for a broad readership in the fields of green chemistry, biotechnology, chemical engineering, and biochemistry, among others. Mara G. Freire is a Coordinator Researcher at CICECO - Aveiro Institute of Materials, Chemistry Department, University of Aveiro, Portugal.

Book Description
The Application of Green Solvents in Separation Processes features a logical progression of a wide range of topics and methods, beginning with an overview of green solvents, covering everything from water and organic solvents, to ionic liquids, switchable solvents, eutectic mixtures, supercritical fluids, gas-expanded solvents, and more. In addition, the book outlines green extraction techniques, such as green membrane extraction, ultrasound-assisted extraction, and surfactant-mediated extraction techniques. Green sampling and sample preparation techniques are then explored, followed by green analytical separations, including green gas and liquid capillary chromatography, counter current chromatography, supercritical fluid chromatography, capillary electrophoresis, and other electrical separations. Applications of green chemistry techniques that are relevant for a broad range of scientific and technological areas are covered, including the benefits and challenges associated with their application. - Provides insights into recent advances in greener extraction and separation processes - Gives an understanding of alternatives to harmful solvents commonly used in extraction and separation processes, as well as advanced techniques for such processes - Written by a multidisciplinary group of internationally recognized scientists

Book Description
Nature provides us with an abundance of chemical potential. Presenting an overview of the use of bioresources in the 21st century, Introduction to Chemicals from Biomass covers resources, chemical composition of biomass, key factors affecting composition, utilization of wastes, extraction technologies, controlled pyrolysis, fermentation, platform molecules, and green chemical technologies for their conversion to valuable chemicals. The text shows how smaller volume chemicals could become bulk chemicals as a result of a greater exploitation of biomass products, making it an important resource for academic and industrial scientists and researchers.

Book Description
This book looks at new ways of tackling the problem of separating reaction products from homogeneous catalytic solutions. The new processes involve low leaching supported catalysts, soluble supports such as polymers and dendrimers and unusual solvents such as water, fluorinated organics, ionic liquids and supercritical fluids. The advantages of the different possibilities are discussed alongside suggestions for further research that will be required for commercialisation. Unlike other books, in addition to the chemistry involved, the book looks at the process design that would be required to bring the new approaches to fruition. Comparisons are given with existing processes that have already been successfully applied and examples are given where these approaches are not suitable. The book includes: - New processes for the separation of products from solutions containing homogeneous catalysts - Catalysts on insoluble or soluble supports – fixed bed catalysts - continuous flow or ultrafiltration - Biphasic systems: water - organic, fluorous - organic, ionic liquid – organic, supercritical fluids (monophasic or biphasic with water, organic or ionic liquid) - Comparisons with current processes involving atmospheric or low temperature distillation - Consideration of Chemistry and Process Design - Advantages and disadvantages of each process exposed - Consideration of what else is need for commercialisation

Book Description
The Earth's natural resources are finite and easily compromised by contamination from industrial chemicals and byproducts from the degradation of consumer products. The growing field of green and sustainable chemistry seeks to address this through the development of products and processes that are environmentally benign while remaining economically viable. Inorganic chemistry plays a critical role in this endeavor in areas such as resource extraction and isolation, renewable energy, catalytic processes, waste minimization and avoidance, and renewable industrial feedstocks. Sustainable Inorganic Chemistry presents a comprehensive overview of the many new developments taking place in this rapidly expanding field, in articles that discuss fundamental concepts alongside cutting-edge developments and applications. The volume includes educational reviews from leading scientists on a broad range of topics including: inorganic resources, sustainable synthetic methods, alternative reaction conditions, heterogeneous catalysis, photocatalysis, sustainable nanomaterials, renewable and clean fuels, water treatment and remediation, waste valorization and life cycle sustainability assessment. The content from this book will be added online to the Encyclopedia of Inorganic and Bioinorganic Chemistry.
